BM3M-TDT1,2 Photoelectric Sensor","description":"\u003cdiv\u003e\u003cp\u003eBM3M-TDT1,2 from Autonics is a general-purpose through-beam photoelectric sensor pair with an integrated receiver amplifier. It uses a 940 nm infrared emitter and detects targets at up to 3 m, with reliable operation requiring alignment between emitter and receiver. The receiver side operates from 12–24 V DC and provides an NPN open-collector output in Dark On mode, so the output activates when the beam is interrupted. Wiring is three-wire: brown is +V, blue is 0V, and black is the load\/output, with a maximum load current of 100 mA. The device supports an operating temperature range from –10 °C to 60 °C. The 3 m sensing distance is specified as 118.110 inches, reflecting the common metric\/inch specification. The BM3M family features a compact, lightweight housing designed for tight automation spaces, typical of Autonics' BM line. Because this is a through-beam configuration, correct emitter–receiver alignment at the 3 m range is essential for consistent sensing performance.\u003c\/p\u003e\u003c\/div\u003e","brand":"BM3M-TDT1","offers":[{"title":"New","offer_id":51677105848622,"sku":null,"price":435.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c67bd731-9f77-4869-8d9f-21043a76b378.jpg?v=1769557879","url":"https:\/\/plgautomation.com\/products\/autonics-co-ltd-bm3m-tdt1-2-photoelectric-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
